| Abstract: | The authors applied an adaptive fuzzy PD controller to a micpneumatic drive consisting of a rodless cylinder,two pressure servo-valves and a microcomputer.Due to the inherent strong nonlinearity it is very difficult to control the cylinder with the desired positioning accuracy by means of linear concepts.The fuzzy PD controller yields a fast and exact positioning of a piston using an adaptive compensation of the friction force of the cylinder. |
